Can anyone help with this problem.....I have a Toshiba RDSX32 DVD Recorder. When I play a backedup DVD, that probably has a reading error on it from backup, I get a message that says Check the disk...It maybe physically damaged or need cleaning. Cleaning does not help. What is so frustrating is that the same disk will play in my cheap $80 Toshiba that I have in the bedroom. I have a service contract on the Recorder. Will taking it in for service help? This problem does not happen all the time just certain times.
